POM has excellent creep resistance but is notch sensitive
Sorun Belirtisi
Although POM is creep resistant, its notched impact strength is low.
Neden Analizi
POM has regular molecular chains and high crystallinity, but the stress concentration effect at notches is obvious and the impact is low.
Çözüm
Avoid sharp corners and notches in design; fillet transitions; use toughened POM grades.
Temel Çıkarım
POM notch sensitivity is a design safety factor requirement.
